MEKA Horizontal Screens Designed For The Toughest ApplicationsMEKA Horizontal Screens are a combination of quality, reliability, and performance; providing a long service life while operating under the most demanding applications.

Nowadays, customers are requiring tighter specifications for products for precisely shaped aggregate or closely-sized stone. As a result, tighter control over the process is of utmost importance and the most effective point to do that is at screening. For that critical step you can trust MEKA Horizontal Screens.

The screens elliptical motion is combined with high acceleration, thereby bringing more power into play than in traditional screens. This ‘’high power’’ feature delivers better performance in terms of both throughput and screening efficiency.

Proven oval stroke design increases production, reduces recirculation load. Oval throw action makes MEKA screens virtually non-plugging and raises quality output. The ability to fine tune stroke angle, amplitude and speed adds versatility in meeting changing screening conditions. Extra-strong body construction, durable bearing mountings, computer designed chrome-moly-nickel gear set with premium metallurgy extend service life.

These screens provide outstanding performance for all screening and can be widely applied in mining, aggregates, and concrete and asphalt recycling. The special applications for Horizontal screens include: when fine screening with a large percentage of near size product, wet washing or when low head room is critical such as mobile mounted equipment.

HORIZONTAL SCREENS


Oval Stroke Geared To ProductivityMEKA Horizontal Screens generate power via three-shaft impulse mechanism located in the centre of the screen body with eccentric counterweights. The combination of the three shafts provide an oval stroke with adjustable amplitude, speed and operating angle, determined by application.

Oval stroke screen action combines the best features of the circle and straight line throw into a unique oval stroke, by benefiting from the screening of the circle throw with the conveying action of the straight line. The motion is nearly vertical through the initial lift phase of the stroke,and the openings in the screen cloth are perpendicular to the material. This provides optimum alignment and maximum probability of material passage through the screen openings.

Adjusting the stroke angle has been found to be the most influential in optimising the screen efficiency. Higher stroke angles increase the number of chances the material has to pass through the openings and also increases the impact to shake fines loose. Lowering the stroke angle increases the travel rate for heavy screening or scalping operations. Higher speed is sometimes desired for scalping duty.

HIGH STRENGTH SCREEN BODYThe body of the screen is extremely strong supporting the stresses required by the high power mechanism. This rigidity is provided by frames made from beam sections with stiffeners positioned in critical areas.

Side plates are made from high quality steel and laser cut holes. Frames are huck-bolted to the side plates insuring structural integrity and eliminate stress fatique in the screen body.

MOTOR BASEThe motor base coupled with the belt tensioning system enables a practical motor assembly and V belt - pulley replacement, and provides energy efficiency by keeping the belt tension at the desired level. In addition, by providing a bolted connection between the motor frame and the main frame, cracks and fatigue issues associated with welding are avoided.

SCREEN DECKSMEKA Horizontal screens can accommodate all media types, wire cloth, urethane and rubber. Steel Wire cloth is suitable for the screening of low moisture materials that are non-corrosive and non-abrasive, and that will not cause clogging or accumulation problems.

RUBBER AND POLYURETHANE SCREEN MEDIARubber and Polyurethane screen media is used for the screening of highly corrosive materials that require high abrasion resistance. They are more resistant to clogging and material accumulation than steel wire mesh.

WET SCREENINGThe washing system has been designed for complete reliability with;

• Replaceable nozzles,

• Inclinable perforated tubes that can adjust the angle of the jets,

• An adjustable valve per spray pipe,

• Sealing boots along the side plates,

• Perforated rubber tubes,

WIRE CLOTH STRETCHING SYSTEMScreen meshes are fastened to the screen body by means of screen clamps and sheet bars, after being well stretched at the edges by the tension sheet. Thus, any slackening of the screen meshes during the screening process is prevented.

MOUNTING ARRANGEMENTThe mounting arrangement of MEKA Horizontal Screens is with coiled springs or with reinforced rubber springs depending on the application.

Coiled spring is used when there is no threat of corrosion or abrasion, when there are plenty of opportunities for maintenance and spring replacement, and when loss of time due to problems caused by spring fracture is not an issue.

Rubber spring should be used when there is a risk of corrosion or abrasion, when there are limited opportunities for maintenance and spring replacement, and where any halt in production will result in significant costs.

Additional benefits;- Lower operation noise,- Increase safety for operators- Smoother shut down of the screen

BEARINGS AND LUBRICATIONSelf aligning taper roller bearings are used to withstand the high thrust and radial loads under which the drive shafts of the triple drive system operate. The roller bearing lubrication is carried out by oil lubrication in an oil bath, which reduces operating temperature for increased bearing life and results in low maintenance.
